THOMAS E. CARPENTER, OF PROVIDENCE, RHODE ISLAND.

EYE GLASS-MOUN TING.

To all whom it may concern:

Be it known that I, TnoMAs E. CARPENTER, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Eyeglass- Mountings, of which the following is a speci- 'lieation, reference being had therein to the accompanying drawing.

Like reference numerals indicate like parts.

Figure 1 is a front elevation of my improved mounting for eye-glasses. Fig. 2- is a top plan of the same. Fig. 3 is a view in top plan of one of the oscillatory nose grips and connected parts as seen in its Wearing position. Fig. 4 is a view of said nose grip and connected parts as seen in its adjusting position. Fig. 5 is a sectional view as seen on line a; no of Fig. 3. Fig. 6 is a view of said nose grip and connected parts as seen in its assembling position. Fi 7 is a view of the same as seen partly in eIevation and partly in section on line 1: y of Fig. 6. Fig. 8 is a view of one of the nose-pads, and the mo unting of the same, as seen partly in elevation and partly in section on line 2 z of Fig. 2. Fig. 9 is a view in top plan of said nose-pad. Fig. 10 is a view of the same, as seen partly in elevation and partly in section on line to w of Fig. 9.

My invention relates to mountings for eye glasses, and particularly to oscillatory lingeroperated nose-grips, provided with swiveling nose-pads; and it consists of the novel construction and combination of the several parts as hereinafter described and claimed.

In the drawings the reference numerals 1, 1, represent the lenses of a pair of eyeglasses. The bridge 2 is arch-shaped and terminates in two straight ends 3, 3. end 3 has the two parallel ears or clamps 4, 5, and the two prongs 6, 6, which latter are adapted to fit upon the edge of a lens 1, and said bridge 2, ends 3, 3 ears 1, 5, and prongs 6, 6, are preferably integral.

Each of the ears 5 has a screw-threaded hole 7 tapped through it and each of the ears 4 has a smooth countersunk bore 8 made through it. A screw 9 passes through each ear 4 and its companion ear 5, the threaded portion of said screw engaging with the threaded hole 7 and the head of the screw 9 being seated in the countersunk portion of the bore 8 of the ear 4. The lens 1 has the Specification of Letters Patent.

usual hole bored through it for the passage of the clamping screw 9.

There are two nosegrips, each comprising a shank or stem portion 10 and an integral bow or finger piece 11. The nosegrip is made of tempered sheet metal and is normally in the position illustrated in Fig. 3. The nose grip as seen in cross section is rectangular or oblong, with the upper and lower surfaces thereof parallel and the edges preferably rounded, and at its inner end is reduced to a cylindrical form, as seen at 12. It is also reduced in width from the place marked 13 in Fig. 6 to the opposite end, ex cept where it is somewhat enlarged to form the shoulder 14-, as represented in Figs. 3, t and 6.

The nose-pads 15 extend diametrically opposite, one from the other, from a short tube or sleeve 16 upon which they are mounted diagonally. Each sleeve or tube 16 has two stop pins 17, 18, extending therefrom. The sleeve or tube 16 is rotatably mounted on the cylindrical end 12 of each nose grip and is capable of an oscillatory movement thereon, limited by the contact of the stop pins 17, 18, respectively, in alternation, with the portion 1O" of the nose grip, as seen in Fig. 8. The outer end of the cylindrical portion 12 of the stem 10 of the nose grip is riveted over to form a head.

A pin 19 is inserted in each end piece 3, or otherwise secured thereto. It has a head, preferably elliptical in form, and. a shank which is oblong or rectangular in cross section.

In assemljiling the several parts of said eyeglass mounting, the nose grip 10, 11, is first placed with one edge thereof in abutment with the shank of the pin 19, as illustrated in Fig. 7 with the open end of the bow spring 11 above and resting upon the head of the pin 19. Then the tip end 20 of the bow portion 11 of the nose grip is sprung out laterally to one edge of the head of the pin 19 and then pressed to a position below the head of said pin and then released, whereupon said tip end 20 automatically and by the resilience of the nose grip springs into the position illustrated in Figs. 2, 3 and 5, and then lies wholly beneath the head of the pin 151. The nose grip is then in contact with two opposite [lat sides of the shank of the pin 19, as shown in Figs. 3 and 5, and the tip end 20 of the how 11 lies in close proximity with the shoulder 13 of the nose grip. This is the normal position of the nose grip, and in this normal position the two shoulders 13 and 14 abut the other two opposite flat sides of the shank of the pin 19, as seen in Fig. 3. In order to place these nose grips in wearing position upon the nose, the person using my said improved eye-glass mounting seizes the two bows or finger pieces 11 by his thumb and forefinger, and pinches them toward each other. By this finger movement the nose grips are operated in opposite directions, and the nose-pads 15, 15, which, as shown in Figs. 1 and 2, are quite close to gether, are moved away from each other.

he movement of one of these nose grips can be understood by a comparison of Figs. 3 and 4. The other of the nose grips operates in the same manner, but in the opposite direction. When the bow 11, shown in Fig. 3, is moved in the direction of the arrow21, the tip 20 of the bow 11 separates from the shoulder 18, as illustrated in Fig. 4, the adjacent parts of the stem 10 of the nose grip and of the bow 11 turning or rocking on the diagonally opposite corners of the shank of the pin, as seen in said figure. Thus the tip 20 of the bow is pried or forced away from the shoulder 13 against the inherent resilience of the spring, and as soon as the fingers release the pinching action on the bows 11, the nose grip automatically resumes its normal position, as in Fig. 3, and thereby the nose-pads 15 press against the nose with sufficient force to hold the eyeglasses safely and securely in wearing posi tion.

The nose-pads 15 have a swiveling action upon the end of the stems 10 of the nose grips, as described, and so automatically adjust themselves to the nose, the oscillatory move ment thereof being limited by the stop pins 17, 18, coming into contact with the stem of the nose grip, as seen in Fig. 8.

It is a peculiar feature of myinvention that the spring-action of the nose grips in opening and closing is always in one plane, as is apparent from an examination and comparison of Figs. 8 and 4. If by continuous wear this spring-action is impaired, such a condition is caused by a partial separation of the tip 20 of the bow 11 from its natural proximity with the shoulder 13, shown in Fig. 3, and it is in stantly corrected by bending said tip and the contiguous portion of the bow 11 manually or by any suitable tool to its former position shown in said figure.

I claim as a novel and. useful invention and desire to secure by Letters Patent 1. In an eye-glass mounting, the combination of a fixed support having a shank which is angular in cross section; a resilient nosegrip having a shoulder near one end thereof normally in abutment with one corner of said pin shank and adapted by its resilience to hold the opposite end against the diagonally opposite corner of the shank and means for giving an oscillatory movement to the nose grip on said pin shank.

2. In an eye-glass mounting, the combination of a fixed support, a pin on the support having a shank which is rectangular in cross section; a resilient nose grip having a shoulder near one of its ends normally in abutment with two contiguous sides of the shank and adapted by its resilience to hold the opposite end against the other two contiguous sides of the shank; and means for giving to the nose grip an oscillatory movement on the pin shank.

3. In an eye-glass mounting, the combination of a fixed support; a pin on the support having a shank which is oblong in cross section; a resilient nose grip having a shoulder near one end normally in abutment with the pin shank and adapted by its resilience to hold the opposite end against an opposite side of the shank; and means for giving to the nose grip an oscillatory movement on the pin shank.

4. In an eye-glass mounting, the combination of a fixed support a pin on the support having a shank which is oblong in cross section; a tempered nose grip having a bow shape intermediate its ends; a shoulder on the nose grip near one end normally in abutment with the pin shank; and a tip at one end of the nose grip normally in abutment with the pin shank opposite to the place where said shoulder abuts the pin shank andin close proximity to said shoulder, said bow serving as a finger piece to give an oscillatory movement to the nose grip and bow upon the pin shank.

5. In an eye-glass mounting, the combination of a fixed support; tempered nose grip having an approximately central shoulder and of a reduced width therefrom to one end; a bow integral with the nose grip and bent into proximity with the shoulder of the nose grip and having a tip end normally in contact with said shoulder but separable therefrom by an intermediate space; a shoulder near the tip end of the bow and located so as to leave a rectangular space between the two shoulders; and a pin upon the fixed support provided with a shank which is oblong in cross section and which passes loosely through said last named space and approximately fills the same, all so combined and arranged that when the nose grip and bow oscillate upon the pin shank the tip end of the bow is pried and moved away from the first named shoulder by the pressure on said shank caused by the oscillation of the nose grip on the pin shank.

6. In an eye-glass mounting, the combination of a fixed support, a pin on said support having a shank which is oblong in cross section and a nose grip having faces which abut said pin shank and provided with a spring bow whose free end has faces which normally abut said shank.

7. The improved eye-glass mounting herein described, consisting of the combination of the bridge 2, having the two ends 3 3; the two lens-holding rongs 6, 6, extending from each of said bridge ends; the two parallel lens clamps 4, 5, extending from each of said bridge ends; and on each of said bridge ends the following named arts, namely; the pin 19 having the shank 0 long or rectangular in cross section; the nose grip 10 having the cylindrical end 12 and the integral bow spring 11 terminating in a tip 20; the shoulder 13 on the nose grip 10; the shoulder 14 on the how spring 11, which two shoulders loosely abut t 1e shank of the pin 19; the sleeve 16 loosely mounted on the cylindrical portion 12 of the nose grip 10; the rivet head on the end of said cyhndrical portion 12; the nosead 15 20 THOMAS E.
